About Converting Cups per Fortnight to Gallon per Minutes
Cup per Fortnight and Gallon per Minutes both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
gallon per minutes = cups per fortnight × 0.0000031001984127
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per fortnight equals 1.955921e-10 base units, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct cup per fortnight-to-gallon per minutes factor of 0.0000031001984127.
Simple example
1 cup/fn × 0.000003100198413 = 0.0000031002 gal/min
1 cup per fortnight = 0.0000031002 gallon per minutes.
Real-world example
60 cup/fn × 0.000003100198413 = 0.0001860119 gal/min
60 cups per fortnight = 0.0001860119 gallon per minutes.

Frequently asked questions
How many gallon per minutes are in 1 cup per fortnight?
1 cup per fortnight equals 0.0000031002 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cup per fortnight to gallon per minutes?
Multiply the cup per fortnight value by 0.000003100198413. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to cup per fortnight?
Use the reverse factor: 1 gallon per minutes equals 322,560 cups per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per fortnight?
Cup per Fortnight (cup/fn) is a unit of flow rate.
What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
Is the cup per fortnight to gallon per minutes conversion exact?
Yes. Both cup per fortnight and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.000003100198413 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
